A petition demanding that a bond order be submitted to the
voters may be filed with the clerk within 30 days after the date of publication
of the bond order as introduced. The petition shall be in writing, and shall be
signed by a number of voters of the issuing unit equal to not less than ten
percent (10%) of the total number of voters registered to vote in elections of
the issuing unit according to the most recent figures certified by the
Bipartisan State Board of Elections and Ethics Enforcement. The residence
address of each signer shall be written after his signature. The petition need
not contain the text of the order to which it refers, and need not be all on
one sheet.

The clerk shall investigate the sufficiency of the petition
and present it to the governing board, with a certificate stating the results
of his investigation. The governing board, after hearing any taxpayer who may
request to be heard, shall thereupon determine the sufficiency of the petition,
and its determination shall be conclusive.
